To all whom it may concern,.-

Be it known that we, ALFRED M. CHAFFEE and llnRBnRTA V. CHAFFEE, bothcitizens of the United Statesresiding at Oxford, in the county ofWorcester and State of Massachusetts, have invented a new and usefulImprovement in Dumping-Wagons for Coal, &c., of which the following,together withthe accompanying drawings, is a specification, sufficiently full, clear, and exact to enable persons skilled in the art towhich this invention appertains to make and'use the same.

The object of our present invention is to provide, in that class ofwagons used for the delivery of coal andother materials, a powerful,ecient and easily operated mechanism for giving a tilting or'dumpingaction to the wagon-body. p Also, to produce alight, strong and durablewagon and to improve the struct- 'ural detail of the mechanism to renderthe apparatus more perfectly adapted!V to the pur- `our dumping wagon.Fig. 2 is a rear end view of the same.

Fig. 2a shows detail of the end gate holder.

Figs. Band 4 show details of the lifter-bar, its supporting roller andconnecf tlons. Fig.`5.is a plan view of the running gear, supportingframe and operating mechanism with the body removed. Fig. 6 is a bottomview ofthe body and delivery chutek attachment. Fig. 7 is a part of thechute in plan view. Fig. 8 is a perspective view of the chuteattachment.

The construction and operation of our dumping wagon are as follows:

A `A denote two longitudinal bearers or sills disposed parallel to eachother at a distance apart corresponding to the width of the wagon-bodyB, and connected togetherrigidly at or near their forward ends bytransom bars a a, which are secured to the center-plate or circle e,whereby the structure is mounted on the swing-frame E carried by thefront axle and wheels W; while at their rear ends said sills A areindividually supported in connection with the rear axle W and wheels W',preferlof one of the sills.

ably on springs S arranged asindicated. The sills are made ofapproximately the same length as the wagon body, say eight feet,

more or less, and are preferably formed of a rectangular wood bar withmetal reinforce plates A attached to the opposite sldes p thereof. (SeeFigs. 3 and l.) Diagonal braces a connect the sills and transom bars aand maintain the parts rigidly square with each other. 'Fixed to andprojecting upward from lbackwardly inclined (see Fig. 1).. .f

A shaft F extends across the front of the `wagonloeneath the body B, andis provided with flanged rollers' F that are supported upon .and rollalong the respective sills A, whichv latter serve as tracks for therolls. Swinging strutsI or' lifting-bars H extend from the ends of theshaft adjacent to said rolls obliquely upward and backward to pivotlstuds G fixed onthe sides of the body near its upper part, as shown;said bars being provided at* their ends with eyes that embrace the shaftand pivot, and form hingingjoints or iiexible connection therewith. Thepivot studs G are best provided with sustaining straps g that aresecured'to and pass beneath the sides of the body, as illustrated. y

' Suitable drag loops I are combined with the `shaftand rolls -F(see'Figs. 3, 4 and 5) carry-4 to be Wound upon or unwound from the sameby rotation of the shaft, which can be elfected by the train ofoperating gears M arranged in connection with said winding shaft andsupported in suitable manner at theouter side Said operating'gearingconsists preferably of the crank receiving arbor m carryinga pinion m',the intermediate gear and pinion fm2 mounted on a stud xed in the frame,and the gear m3 fixed on the end y of the winding shaft, said gearsmeshing together as shown in Figs. 1 and 5. Astop dog IOO fr is providedfor locking the gear train to retain the mechanism at any position ofadjustment.

The winding shaft K is best provided with collars f that are rigidlyfixed on the shaft and embrace the ends of the bearing boxes forretaining the sills against lateral displacement in relation to eachother, thus avoiding the necessity of other framing therefor than thefront transoms a.

Beneath the body there are two forwardly extending push-bars or rods Lthat have their rear end pivoted to an nn'der part of the body at L',and their front end formed with atransverse eye L2 through which thechain J is rove, as indicated in Fig. 5.

The rear part of the body is provided with laterally projecting studs Cvthat extend through the slots clin the bracketsfor hinging and retainingthe body in connection with the sills; said studs being best providedwith caps that prevent lateral spread of the frames. The studs C andbrackets D also hold the body from swinging sidewise at its forward end,the bars H in a measure assisting to keep the body in proper lateralalignment.

When in normal position the body rests at its rear end on the sills Aand at its front end on the rolls F which lie on the sills at theposition shown in full lines Fig. 1; the studs C occupying the lower endof the vertical portion of the slots ci in the guide brackets D.

In the operation for tilting the Wagon body, the operator places thecrank h on the arbor m and by means of the crank and gear-train Mrotates the winding-shaft K, winding in the chains J thereby drawingbackward the shaft F to which the lift-bars H are connected the rolls Frunnin g on the sills A causing the inclined lift-bars to assume a morenearly upright position and consequently elevatiiig the front end of thebody while the rear end rests upon the sill (see dot-and-dash lines Fig.1). When the body has reached the position indicated at B4 the rings i,or suitable stops on chains J engage the eyes L2 of the push-rods L.Also at such position the studs C have risen in the slots d totheinclined portion thereof; then the further winding in of the chain Jwhile further elevating the lift-bars H also at the Sametime forcesbackward the pusli-rods L that are attached tothe body at L', thusmoving the entire body rearward and causing the studs C to slide up theincline slots d thus effecting the elevation of the body to the positionindicated at B5 on Fig. 1,'by dotted lines. The contents of the wagoncan thus be dumped by releasing the end board B', or delivered throughthe endgate into the chute to be thereby conducted into the coal-hole orplace of deposit. By reversal of this operation and the unwinding of thechains J the wagon body is readily let down to its normal position. Bymeans of the rolls F traveling upon sills A, and the lift-bars H actingin conjunction therewith and the pivots Gr, a very powerful, efficientand easily operated apparatus is produced. Also, by the arrangement ofthe bars L and slotted brackets D the elevation of the body can beeffec-ted in an automatic and highly satisfactory manner. y

By making the slots d vertical at their lower ends the body is retainedagainst rearward movement until its forward end has been elevated to thedesired degree and until the rings I have been drawn back to meet theeyes of the push-bars, thus rendering the operation more perfectly undercontrol and regular in its order of action. Y

It is obvious that the rollers, lifting bars and winding chainappliances may be employed without using the slotted brackets D, thebody being simply hinged at its rear end to the sills, or with the studsO serving merely as stationary .pivots instead of movable pivots; sucharrangement may, in some instances, be employed but does not affordelevation at the rear of the body and is not therefore deemed asdesirable as the form shown with the brackets vertically and obliquelyslotted. The body is best provided with metal chateplates b along itslower part where the lifting bars H strike the sides thereof in thevarious positions of elevation.

The rear end board of the body is hinged to swing downward and is alsoprovided with a delivery opening and closed by a sliding gate B2 asindicated; this gate we provide with notches n in one side (see Fig. 2?)and combined therewith we arrange a spring holder N having a flatportion that screws onto the frame, a spring portion n and a bolt ornose n2 that extends through the frame and engages the notch in theslide, and a thumbflange n3 for retracting the bolt.

Underneath the bottom of the body B we provide two parallel rods R Rsecured only Vat their front and rear ends to the body frame,

but also permits of the chute being swung to a position of right or leftinclination, as indicated by Fig. 7. When under thebody the IOO rear endof the chute P is suspended by a 'to more clearly illustrate the actionof the wagon-body adjustment and the mechanism for effecting the same.

What we claim, and desire to secure by Let- .ters Patent, is-

1. In a dumping wagon the side brackets having the slot therein for thebody-retaining studs shaped as shown, thelower part of said slot toresist backward movement of the stud until. the wagon front is at agiven degree of elevation, and the upper part to afford backward andupward movement thereof; in combination with the sills, liftingmechanism mounted thereon for elevating the body, and

. push-bars engaged and actuatedby said liftthe rollers and rol1-shaftcarrying the lower ends of said lifting-bars, said rollers running uponsaid sills as a track, the windingshaft, y y

the chain connecting said rollers and lift-bar carrying devices withsaid winding-shaft, the push-bars pivoted to the body and having eyesthat engage with said chain, and the crankactuated gearing for rotatingsaid windingshaft, substantially as setforth.
